The Jukar Derringer is a replica black powder pistol often produced in Spain, typically modeled after the classic American derringer design. The serial number 051291 suggests it is a specific unit, but detailed information about that exact firearm may be limited. These pistols are generally valued for their craftsmanship and can be used for historical reenactments or collection. For precise details, including potential value or historical significance, consulting a firearms appraiser or a specialized collector's guide is recommended.
The PY in the middle of your serial number dates your pistol to 1982.
I was told by a gun collector that a five digit number on an imported derringer is not a serial number- it is a lot number ( a serial number should be at least 6 digits) what about the proof markings on the gun? can this identify the company or date or just the country of origin?
These are kit guns sold mostly in the 70's and 80's They usually go anywhere from 50-75 dollars depending on the condition.
